Intermediate SEO question on sub-domains

[white_r]

Season's greetings

Before I get into my question, I would like to thank everyone in the forum for providing great IM tips and info to helping me succeed throughout the year. I have been lurking in the forums for about a while now and I learned lot about SEO, copywriting and email marketing.

Recently, I been hired by a company to help with their Marketing/SEO - pretty much what you guys do, except for a company. Long story short, I managed to get the keyword(s) they wanted on the first page of Google.

But here's my problem...

The page that has been listed on the first page of Google is a subdomain rather than the homepage.

From an SEO perspective, it doesn't really matter because a page is a page and I'll take what I can get. But from a marketing perspective, it affect conversation rates, bounce rates and bottom line.

So far I have done SEO all the internal pages that matter. I have also built hundreds of external links through articles, blog comments, social media and more - for my homepage specifically.

My question is, why does the sub domain appear on the first page of Google despite all my link building efforts to the homepage? The homepage also has a page rank of 5 while the subdomain has a page rank of 2. None of this makes sense.

The only explanation I have is that the subdomain has more contents and texts so Google calls in for more keywords. But other than that, I have done zero SEO for the sub-domain.

Please point me to the right direction.

Happy holidays and have a wonderful new year!

Does not matter if it's a subdomain or the main domain.
The SEO is the same.

Whether people buy would depend on your sales pitch on the page.

Google picks relevant pages. Not the page with the most backlinks.
If your subdomain is more relevant and better, well, there you go.

If people did not care about about visiting subdomains, then sites
like ESPN would get no visitors.
